The Rolling Seas essence - I filled the water to it's highest point and forgot to get the last key and so now i can't go move the blocks to get to the red switch and lower the water. I'm stuck with the water too high because i have to move a block to get to the red switch, and i can't move the block under water to get to where i need to lower the water. Make sense? Do you know how to fix this or maybe "restart" the dungeon? Please help
